IMPROVEMENT IN EARTH-CLOSETS.

The Schedule referred to in these Letters Patent and maldng part of thesame.

To all whom it may concern:

Be it known that I, EDMUND GRLFFITH, of Wilmington, Delaware, haveinvented certain new and useful Improvements in Earth-Closets, of whichthe following is a specification.

Nature of 'the Invention.

My invention relates to that class of earth-closets in which the earthis fed upon the excreta by the raising and lowering of the lid andconsists in First, a vacuum-board suspended in the hopper, by means ot'which the earth is prevented from being clogged; and

Second, in the devices by which the earth is fed upon the excl-eta inany desired quantity, as will herealter be more particularly described.

Description of the Drawing.

Figure l is a sectional view of my closet, showing the lid down upon theseat and the position of the various devices prior to the closet beingused.

Figure 2 is a similar view of the same, showing the lid up and theposition ofthe devices while the closet is in use.

Specification..

A represents the frame of my closet;

B, the hopper;

U, the lid; and

D, the seat, these parts being constructed. in the usual manner. g

Secured to the back part of the lid C is a hook or eye, a, which servesto operate both the slide l and shoe G through the connecting-rods c e.

The slide H moves hack and forth in grooves immediately below the hopperB and just above the chute F, upon which the earth slides to the pail K.

To the lower end of the chute is pivoted a shoe, G, which serves tospread the earth completely over the bottom ofthe pail when lowered, andto form a chan1- ber, I, at the end of the chute for the reception ofthe earth as it issues from the hopper when up, until theV closet hasbeen used and the iid closed.

Secured to each end of the shoe is the connectingrod e, which has vanelongated loop formed ou its upper end so as to catch in the eye a onthe back ot' the seat C.

W hen the scat is being raised or lowered it passes through nearlythree-tburths ot' its distance before the eye a reaches either end ot'theloop, when it suddenly reverses the position of the-shoe.

Suspended in the hopper B is a vacuum-board, L, which moves i'eely backand forth oil its pivots.

When the earth is placed in the hopper its downward pressure serves'topack and clog it at the lower end, where it is small and contracted. Asthe earth begins to run ont on the opening of the slide Hit causes amovement from one side to the other of the board L, and this movement,producing.;` a vacuum, draws the earth from the sides of the hopperwhere it is most likely to stick.

M is adoor or opening in the back part of the closet, so as to giveaccess to the various parts for repairs.

Having thus described my invention, Y

What I claim as new, and desire to secure by Letters Patent, is

1. lhe cover .0, the eye a, the slide H, and rod c,`

in combination with the shoe G and rod e, having a loop formed on itsupper end, when all are combined and arranged in the manner described.

2. The vacuum-board L, when arranged to operate substantially as shown.

3. The board L, hopper B, slide H, rods c e, eye a,

lid C, and shoe G, when all are combined as specified.

In testimony that I claim the foregoing I hereby affix my hand.
